Answer: x = 12.124
y = 14
Step-by-step explanation:
In a 30, 60, 90 triangle, the side opposite the 30° angle is half the length of the hypotenuse. So y = 14.
7/sin(30) = 14
You can use the Pythagorean Theorem to calculate x.
14^2= 7^2 + x^2
196 - 49 = x^2
147 = x^2
sr/rt 147 = sq/rt x^2
12.124 = x
Or with trig
7/tan(30)= 12.124
For this case, the first thing we must do is define variables.
We have then:
x = pounds of type a coffee
y = pounds of type b coffee
We now write the system of equations:
5.95x + 4.45y = 490.05
y = 2x
Solving the system of equations we have:
x = 33
y = 66
Answer:
were used 33 pounds of type a coffee
Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} (F - G) (6) =

G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)}
F(6) = 8
G(6) = 9
